Comstock/Thinkstock(AURORA, Colo.) -- A pair of Colorado cops and two Good Samaritans rescued a mother and her 2-year-old daughter by lifting a car off of them following an accident.

Sgt. Jon Kessler, an off-duty police officer who was working security at a Walmart across the street, on-duty Sgt. Matt Brukbacher and several civilians performed the rescue Monday night in Aurora, Colo.

Kipinga Muanza Kalala, 37, was crossing three lanes of traffic with her daughter, Angela, and her 4-year-old twin sons, Jack and Vic, when they were hit by a car driven by Michael Lovato, according to the Aurora Police Department.

The mom and daughter were trapped beneath the Kia Rio car, according to the Aurora Police Department.

Lovato, 52, didn't see the family crossing in time to stop. ABC affiliate KMGH reports there was no crosswalk or pedestrian signal where the Kalala family was crossing.

The two sergeants and two bystanders lifted the nearly 2,500-pound car. Kessler rescued the toddler, while Lovato pulled the mother out from underneath his car, according to the Aurora Police Department statement.

The twin boys were not under the car, said Aurora Police Department spokesman Officer Frank Fania.

Kalala and her three children were taken to the Aurora Medical Center South. The mother is recovering in the intensive care unit, having suffered a head injury as well as several broken bones.

Her daughter, who suffered lacerations, abrasions, and bruises, is still in the hospital. The twin boys were released after being examined, and did not suffer any major injuries.

The Aurora Police Department has asked the Good Samaritans to come forward.

"It should be noted that their contributions to the positive outcome of this potential tragedy cannot be overlooked. Their actions directly impacted the mitigation of a very precarious situation and I would deeply appreciate any acknowledgement of them," said Department spokesman Lt. Chuck DeShazer.

Lovato will not be charged, according to the Aurora Police Department.
